9 Claims.

My invention relates to a paper cutter of the type commonly known in the trade as a gravity cutter. It has particular reference to a paper cutter in which provision is made for locking the paper roll stick in position in the saddles on the standards, and also for holding the paper knife upward out of the path of the roll of paper while being placed in position on the standards.

Another and further object of my invention is the provision of a locking member which is simple in application, which eiectively holds the roll stick in position on the standards, and which by its own Weight automatically seats in position to hold the roll stick in position while paper is being used from the roll.

Another and further object is the provision of a paper cutter having means thereon which is adapted to hold the roll stick in position on the saddles so that all of the paper from the roll Ycan be used instead of, as is the practice at the present time, not attempting to use the last remaining portion of the paper because of the difficulty of holding the small roll of paper on the paper cutter.

With my improved device the roll stick is held in position on the paper cutter until all the paper is removed from the roll stick and in this manner ansubstantial saving is effected over the practice now commonly followed in the use of these paper cutters.

Another and further object of the invention is the provision of a locking member mounted on the standards, with a cooperating seat portion formed on the knife whereby the knife can be held out of the path of the roll of paper as it is being placed upon the cutter. It is a diicult task for the operator to hold the knife on these gravity paper cutters out of the path of a roll of paper being placed on the cutter, particularly if the roll of paper is heavy. With my improved device this operation is easily accomplished so that the operator is free to use both hands in placing the paper in position and there is less liability of injury to the operator as a result of the use of this improved device.

Another and further object of my invention is the provision of a latch member placed upon the standard in such position that it normally functions to lock the roll stick in position on the standard, and upon being turned in an upward position during the changing of the roll, automatically holds the knife out of the path of the roll of paper as it is being placed upon the standard. In providing means for locking the roll stick in position in the saddles on the cutter, the

l I6, I6 pass through the member therefrom, and upon `roll is held in fixed position so that there is no possibility of the roll of paper being pulled out of the cutter and falling down on the operator, injuring the operator, as has happened in the past, particularly with respect to rather large rolls of paper mounted on these cutters.

These and other objects of my invention will be more fully and better understood by reference to the accompanying sheet of drawings, and in Which- Figure 1 is an elevational View of a paper cutter embodying my invention;

Figure 2 is a transverse sectional View showing the holding device in position to hold the paper roll in position on the standard; and

Figure 3 is a view partially in elevation and partially in section of my improved device in position to hold the knife out of the path of the paper roll.

Referring now specically to the drawing and in which like reference characters refer to like parts throughout, a pair of standards Ill and II are provided having foot portions I2,v I2 through which screws I3, I3 may pass in order to secure the cutter on a shelf, counter or the like, in position to hold a roll of paper from which sections can be removed for use in wrapping bundles, packages, and the like. The usual cross member I4 is` provided which is tted upon horizontal portions I5, I5 integrally formed with the standards I0 and II at the upper ends thereof. Bolts I4 and through the portions I5 so that the standards I0 and II are held in upright position and in proper spaced .relation with each other to accommodate rolls of paper of predetermined width. Slots II, II are provided in the portions I5, I5 through which the bolts I6 pass, which allows for a slight adjustment of the standards IIl and II toward or away from each other to provide for rolls of paper of slightly varying width.

A knife I8 of the gravity type is provided, having arms I9, I9 at each side thereof, with openings 29, 20 at the upper sides thereof adapted to nt over studs 2|, 2| formed at the sides of the standards I0 and II and projecting inwardly which the arms I9 of the knife I8 are pivotally mounted. Also integrally formed with the standards I9 and I I on the inner opposed sides thereof is a pair of saddles 22, 22, open at their upper sides. The roll stick 23 of the paper roll 24 is adapted to rest upon the saddles 22, 2'2 to support the roll of paper 24 upon the standards I0 and II.

The device described up to the present point is the common, ordinary paper cutter of the gravity type which is old and well-known in the art.

My invention has to do with an improvement upon the parts heretofore described. It com-prises a pair of locking members 25, 25 which are pivotally mounted upon inwardly projecting studs 25, 26 formed on the inner side of the standards I and Il and placed intermediate the tops of the saddles 22, 22 and the studs 2l, 2| upon which the arms of the paper knife are mounted, so that when the locking members are placed in vertical position, as shown in Figure 2, the lo-wer ends of these locking members terminate immediately above the roll stick 23.

paper roll is in position on the standard -and paper is being removed therefrom for wrapping purposes, and the like. The locks 25 are held on the studs 26 by means of cotter pins` 21,21, so that the locking members 25 are free to rotate in a complete circle about the studs 26. They will not slip off, but may be removed' from the'studs by the removal of the'cotter'pins 21,

for 'the purpose of replacing them. should they can be lifted up and placed invpositionY against the seats 2Q and the knife allowed to rest by its own weight upon the latch members, thereby holding the knife out of the path of the roll of paper 24 as it is being mounted upon the cutter, particularly as sho-wn in Figure 3. Inthis manner the knife is held completely out -of the way of the operator when a roll of paper is being placed on the standard.

'After the paper has been placed in position, the operator by slightly lifting the outer edge of the knife frees the locks 25 so that they can be turned into a downward position and come to the position shown in Figure 2 in the drawing, immediately above the ends of the roll stick 23,

vwhich holds it securely in position upon the saddles until the lock members are turned to one yside sufficiently so that the roll stick can be lifted out of the saddles 22. It will be understood that the roll stick 23 projects slightly above the ends of the usual paper roll and that the projecting lower ends of the lock members 25 are approximately flush with the inner edges of the saddles 22, so that the paper roll is free to turn on 'the saddles 22 without any interference from the locking members 25, 25.

that when it is desired to place a roll of paper, usually wrapping paper and the like, upon the cutter, the knife is lifted to the position shown in Figure 3. The locking members 25 are turned to a vertical position so that the seat portions of the knife rest upon the ends of the locking mem.- bers 25, thereby holding the knife out of the path of the roll of paper as it is placed upon the cutter. The empty roll stick is removed` from the cutter and a new roll of paper placed thereon, with the roll stick in the saddles as shown in the drawing. Thereupon the operator lifts the. knife slightly and turns the locks into a downward position so that the ends overlap the ends of the roll The roll stick is thus held in position during the time whenthe In operation the device is exceedingly simple inE stick. The knife is dropped so that the cutting edge thereof rests against the outer surface of the roll of paper in position for use. I'he locks are left in this position during the removal of paper from the roll, which in common practice is done by grasping the free edge of the paper and pulling upon it, thereby unrolling the paper until a sufficient length has been secured. The paper is then pulled sideways and cut -by the edge of the knife I8 anddetached from the roll.

In pulling on the rollof paper bythe free edge, the operator ofttimes in a hurry will pull the paper quickly or give it a decided jerk, which sometimes causes the roll to be pulled out of the saddles and roll from the paper cutter, sometimes vonto the operator in such manner that great inconvenience is caused and also injury has resulted'from this source. Through the use of my device the paper stick is held in position until the paper is entirely removed from the roll stick.

With present devices because of thev inability of the operator to keep the roll stick in position in the saddles when the rollV of paper is quite'reduced in size, it is common practice to remove "from the standards thefsmall roll of. paperv remaining and to throw it away, resulting in a loss of paper. This amounts sometimes to as muchas ten percent of the whole roll, so that in addition to providing a factor of safety through `the use of my improved device, a saving of paper is also effected.

While I have described more or `less;A precisely the details of construction,'I do `not wish to be .understood as limiting myself thereto; as I contemplate changes in form andthe proportion of parts and the substitution of equivalents as' circumstances may 4suggest or render expedient vwithout departing from the spirit or scope off my invention. v
